CONDENSER.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application led February 6,1907. Serial No. 356,016-

To all whom it may concern:

Be it known that I, OsCAR ALFRED NENNINGER, a citizen of theUnited States, and a resident of El Paso, in the county of El Paso and State of Texas, have invented an Improvement in Condensers, of which the following is a specification.

My invention is an improvement in condensers and consists in certain novel constructions and combina tions of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof, Figure l is a front view of my improvement; Fig. 2 is a vertical section; and Fig. 3 is a transverse section on the line 3-3 of Fig. 1.

My invention is adapted to be used in combination with an ordinary house boiler A, supported upon the -usual stand a and provided with pipes a and a2, leading to and from the water back respectively, the pipe a2 being provided with the usual faucet a4 for drawing off water from the boiler.

The improvement comprises a jacket B for the boiler, and a water condenser C in connection therewith. The jacket B is connected with the boiler in any suitable manner, and is provided with a iianged opening b in the lower end thereof for receiving the pipe a2, and with an air vent b2 near its upper end, and on the opposite side from the air vent b2 is provided a flanged opening b3 at the top and bottom for a purpose to be hereafter described.

The condenser O comprises inner and outer concentric shells or casing c, c, the outer casing being provided with upper and lower flanged openings c2 connected in any suitable manner with the flanged openings b3 of the jacket, whereby to provide communication between the jacket and the outer casing. At its lower end the outer casing is provided with a short sec.- tion of pipe c0 threaded into one of the branches of a T-joint c3 interposed in the pipe a2 before described, the opposite branch of the T-joint having threaded therein a section of relatively small pipe c5 extending through the pipe e0 into the inner casing c of the condenser, and provided with a faucet c4 as clearly shown in Figs. 1 and 2. The outer casing is also provided with a valved discharge pipe c6 at its lower end, and above the discharge pipe is a laterally projecting section of pipe c7 of relatively large diameter, into one side of which is threaded a steam inlet pipe cf and through which extends an air inlet pipe cs of relatively small diameter, the steam passing through the inlet pipe e9 acting to inject air through the air pipe o8 in a well understood mnner. l Y

A reducing joint c10 is threaded on to the upper end of the inner section as shown in Fig. 2, and a T-joint ou is threaded onto the outer end of the reducing joint, one of the lateral branches of the T-joint being closed by a plug c, and the other branch having threaded thereinto the cold water :inlet pipe fr3 of the house boiler. A cold water inlet pipe C12 for the condenser is threaded into the upper branch of the T-joint and communicates with a pipe cl3 connected with the water main, and provided with a faucet c14 for controlling the flow of water therethrough. As will be evident irom inspection of Fig. 2, the cold water linlet pipes cl2, a3, extend a considerable distance into the inner casing of the condenser and the house boiler, respectively, in order that they may deliver the cold water below the upper portions thereof.

The house boiler A is provided with a hot water discharge pipe a5 provided with a faucet a, by means of which the hot water may be drawn 0H from the boiler for domestic purposes.

In operation, steam from an ordinary tea kettle, or other vessel on the range, is admitted through the pipe e9 into the outer casing c oi the condenser, drawing therewith a supply oi air through the pipe c8 whereby to aerate the steam. On its entrance into the outer casing, the steam comes into contact with the cool wall oi the inner casing o and is partially condensed, the remainder of the steam passing through the openings between the condenser and the jacket into the space between the jacket and the house boiler, where the condensation is completed, the heatedv air passing out through the vent b2, the water of condensation being drawn off through the valve c3. When the Water in the inner casing of the condenser becomes heated, cold water is admitted from the main through the pipe cl3, and the heated water is driven into the house boiler A, passing upward through the reducing joint cm, T-joint cu, and inlet pipe a3, it being understood that the faucet a6 is open during the admission of the cold water to withdraw a proportionate amount oi heated water from the house boiler. The steam and heated air in the jacket assist also in warming the water in the house boiler. The water may also be withdrawn from the inner casing of the condenser by opening the faucet c4 in the pipe c5.

I claim:

1. The combination with the house boiler, provided'with Water circulation pipes for connection with a water back, of a condenser comprising concentric inner and outer casings, said outer casing having a Valved discharge pipe, and a relatively large steam inlet pipe, a relatively small air inlet pipe concentric with the steam inlet pipe, said inner casing communicating` at each end with the corresponding end of the house boiler, a cold Water inlet pipe at the upper end of the inner casing, an outlet pipe at the lower end thereof, a jacket for the boiler provided with an air vent at the top thereof, and communications between the jacket and the outerv casing of the condenser at the top and bottom thereof.

2. The combination with the house boiler, of a. water condenser comprising` concentric inner and outer casings, said outer casing having a valved discharge pipe and a steam inlet pipe, said inner casing communicating at each end with the corresponding end of the house boiler, a cold water inlet pipe at the upper end of the inner casing, a

valved outlet pipe at its lower end, a jacket for the boiler provided with an air vent, and communications between the jacket and the outer casing of the condenser at the top and bottom thereof.

3. The combination with the house boiler, of u water condenser comprising concentric inner and outer casings, said outer casing having a valved discharge pipe, and a steam inlet pipe, said inner casing communicating at each end with the corresponding end of the house boiler, a cold water inlet pipe at the upper end of the inner casing and extending thereinto, and a valved outlet pipe at its lower end.

4. The combination with the house boiler, of a water condenser comprising concentric inner and outer casings, said outer casing, having a valvecl discharge pipe, and a steam inletI pipe, said inner casing communicating at each end with the corresponding end of the house boiler, und n cold water inlet pipe at the upper end of the inner casing. 5. The combination with a house boiler, of n jacket for the boiler, a water condenser comprising concentric inner and outer casings supported by the jacket, said outer casing having a valved discharge pipe und a steam inlet pipe and communicatingwith the jacket :it its top and bottom, said inner casing communicating :it cach end with the corresponding end of the house boiler, :1nd a cold water inlet pipe at the upper end of the inner casing.
